Roof Ring Placement
The roof ring is a tubular ring bolted to the exterior of the roof.
The placement location and quantity of roof ring kits vary with the size of each bin. The exhauster roof ring
(A) on the 135 ft bin will be installed in the seventh roof panel rib hole from the top. The eave roof ring (B)
will be installed in the last roof panel rib hole located at the eave end of the bin.
NOTE: If ladder steps have been installed, and not already omitted, remove the ladder step that is installed
in the same roof panel rib hole in which the roof ring will be installed.
